Fix type names for function references (#1787)

This requires `Type::GetName` to return to be dynamicllay created and
return `std::string` rather then a `const char*`

As this diff shows this type name is only used in textual output and
error messages so should this change should not have a effect of binary
parse time or the interpreter.
